Abstract
Acute colonic pseudo-obstruction (ACPO), or Ogilvie's syndrome, is an acute colonic dilatation without mechanical obstruction; it is most commonly seen in severely ill or postoperative patients. While this syndrome has no clear pathophysiology, it is diagnosed when the cecum and right colon expand without physical obstruction. This condition can lead to perforation and intestinal ischemia. Ogilvie's syndrome is associated with a relatively high morbidity and mortality rate. The diagnosis of ACPO can be often missed due to its vague symptoms such as bloating, abdominal distention, abdominal pain, nausea and vomiting, and severe constipation. We report the case of an 82-year-old female patient who had a unique diagnosis of ACPO, or Ogilvie's syndrome, overshadowed by the diagnosis of severe constipation. This case highlights the importance of maintaining a high index of suspicion and early diagnosis of symptoms that can rapidly become dangerous.
